JRE ''EXCEPTION_ACCESS_VIOLATION'' error

Post by David1998 »

Hi,

After I found some tutorials like this one:
https://www.mydronelab.com/blog/arduino-quadcopter.html

I wanted to try to make such an Arduino quadcopter, as it seems very easy as described in the tutorial. I wanted to use an Arduino Nano and I bought various IMU boards (GY-85, MPU6050, also this one: https://www.ebay.com/itm/9-Axis-IMU-LSM ... 2749.l2649)

Selection for any of the IMU boards, compiling, and programming my Arduino works fine. When I open the MultiWiiConf GUI, I can connect via the COM port. However, once I press the "Start" button, the program stops and I see that a .txt file is generated:

Some error on the rxtxSerial.dll file?

I cannot find out what the problem exactly is. Anyone who has seen a similar error, and could perhaps help me to solve this? The MultiWii looks very promising to me, always wanted to try building a homemade quadcopter, but unfortunately, so far it does not work.

Hi Patrick
The software still does not work. The Multiwii executable doesnt launch when I use your copy of the rxtxSerial.dll. Any suggestions?

Thanks.

Hi David, were you able to solve the problem and get Multiwii to work? I'm currently having the same error and it's extremely frustrating with no solutions.
